Disk units store data for i5/OS™ logical partitions. You can configure disk units into auxiliary storage pools (ASPs).
Disk units store data for i5/OS logical partitions. The server can use and reuse this data at any time. This method of storing data is more permanent than memory (RAM); however, you can still erase any data on a disk unit.
Disk units can be configured into auxiliary storage pools (ASPs) on any logical partition. All of the disk units you assign to an ASP must be from the same logical partition. You cannot create a cross-partition ASP.
You can also create an independent ASP. An independent ASP is a collection of disk units that can be taken offline, or made unavailable, independently of other disk pools because the data in the independent ASP is self-contained. The independent ASP can also be brought online, or made available, while the system is active, without having to restart the system. For more information about ASPs, see the i5/OS Disk pools topic collection.
